MAX HERBKOVITZ, OF CHICAGO, ILLINOIS, ASSIGNOB TO PEERLESS LIGHT COMPANY, OF CHICAGO, ILLINOIS, A COBPORATION OF MAINE.

ELECTRIC-LIGHT STRUCTURE.

Application filed April 28,

To all whom it may concern Be it known that I, Max linnskovrrz, a citizen of the United States, residing at (hicago, in the county of Cook and State ol Illinois, have invented a new and useful Improvement in Electric-Light Structures, of which the following is a specification.

My invention relatcs more particularly to the connection of an upright provided with means for supporting an electric lamp. with a base-section, as for example in a socalled upright electric lamp; and also to a cluster socket construction for receiving and holding a plurality of electric lamps; and my primary objects are, "enerally stated. to provide,novel and simple improvements in the structures above referred to, to the cnd that structures of this character will he g nerally improved as to structure and rendered more economical of construction.

Referring to the accompanying drawings:

Figure 1 is a broken view in vertical. sectional, elevation, of an electric light straw ture shown as an upright lamp structure embodying my improvements.

Fig. 2 is an end view' of thc uppcr portion of the upright of the Strncturc. showing'the electric lamp-rccei ring socket therein, in section. the section being takcu in thc plai'ie oi the mcaus securing the socket in position.

Fig. 3 is a plan view of the ilangcd shell mounted in the uppcr portion of the hase lncinhcr of the lamp of Fig. 1.

Fig. 4' is a view in clcvation. partly hrokcn away. and with its lowcl' end shown in sec-- tion or the upright of Fig. 1 showing a modification of thc lowencnd of this up right. whcrchy this portion of the. upright presents an electric. screw plug:

And Fig. 5, a view in vertical. sectional. clcvution, of the upper end of the hasc mc|uhcrol' the lamp structure, mfitllfit'll to form an electric socket for receiving. and making electrical contact with. the lowcr cud of thc upright of Fig. 4. 7

Referring to the construction shown in Figs. 1. 2. and 3. the hasc of a lamp is rcprcsentcd at (i. this hasc hcing made of any suitahlc material. as for example. wood. and containing a passage thcrcin n-prcacntcd at 7 for thc clcctric-currcnt conducting wires. This passage may extend continuously through tlic hase from top to hottoln or it may opcu at its lowcr end through the side Specification of Letters Patentl Patented Dec. 7, 1920.

of the hasc if dcsircd. The top of the bflSt. presents an upwardly opcning recess 8, which. hy prci'crcnce. alincs with the possage T and is of slightly greatcr diameterthan the passage 7. Extcnding downwardly into the recess H is an intcrnall thrcaded sln-ll Si. preferably formed of shcetnictal spun. or othcrwisc operated on, to prcscnt thc internal thread referred to, the upper end of shell L carrying an outwardly. extending tlangc 1H preterahly ol' annular shape as represented. the shell 9 being rig idly sccurcd to the base in the rcccss 8 as shown. as h mcans of fastening devices, illustrated as nails ll. which pass through openings l! in the flange 1'] and cxtend into thc upper part of the hasc (I. the flange H resting against tlu' uppci' surface ot the hase.

The upright portion of the lamp is represented at 13 and. by preference. is conslrnctcd of mctal to provide the tubular u 'iright section 14 opening into a head 15 prclcrahly formed as an integral structure and presenting the tuhular portions 16, shown as two in numher though the number thereof may he varied as desired, which cxtend outwardly from the median line of the upright ]-l and prcl crahly downwardly inclined in an outward direction. The upper end of the head 1.- is formed with a...

scat 17 for receiving a shade (not shown) which would he held in place by engagelucnt with thc hcadcd portion 18 of a ihrcadcd rod [9 screwing in a threaded opcning i l in the uppcr end of the head.

The lower and of the upright 13 .is ester nally scrcw-threadcd, as indicated at 21, to adapt it to ho screwed into the threaded shell 9; the upright 13 at the upper part of the threaded portion 21. heing equipped with an annular flange 22 which hears against and extends across the flange 10.

Thc socket portions 16 a re provided for recciring the electric-hnnprecoiving sockets and holding them in position. By preference the lain rrccciviug sockets represented at 23 are of any suitahlc construction, such as is commonly provided, and formed with a cantcr contact and threaded socket shell forming the other contact of the socket, with the metal casing of the socket in place thereon. in other words the sockets as shown are such as are ordinarily rovidcd, with the end cap removed, these soc ets being inserted into the open ends of the sockets l6, and preferably against stops as for example. as indicated at 24, the sockets 23 being rigidly secured in the sockets 16. The means shown, and which I preferably employ, for securing thesockets 25! in place obniprise lugs 25 formed on the interior of thosockcts 16 in position to engage with the walls of the openings 26 preliminarily formed in the outer casings oi the sockets 23. and at s rews 27 engaging threaded openings in the sockets 10 and screwing down upon the casings of the sockets 23. ln the assemhlin of the sockets 23 with the sockets 16, the ormer are inserted into the latter to a position in which the lugs 25 extend into the openings 26, the screws 27, in the alincment ot' the sockets 23 with the sockets 16, being screwed down against the sockets 23 to rigidly hold them indjlacc.

The cuwent-conducting wires represented at 29 and 29 and which are electrically con-- nci-ted with the interiors of the sockets 23, extend upwardly through the passage 7. tube l1 and into the head 15 whc-rc they connect with the sockets.

The wiring of the lamp may be in accordance with any suitable plan, and if desired the upright 13 of the lamp may be prelimi narily wired with the ends of the wires pro jecting through its lower end, these wires being spliced with ci'irresponding wires passed through the base 6, the upright 'l i in such case being provided as a preliminarily-wired structure for ready assembling with any one of a number of different varieties of bases 6.

The construction illustrated in Figs. 4 and F) is substantially the same as that illustrated in the preceding figures, except that the base (I and the upright iii are provided with electric socket and scrcxwplug members. respec' tively, these parts being preliminarily wired and the screw-socket oi the base receiving the threaded plug of the. upright for rigidly securing thesc parts together. in this constrnction the recess F4 in the upper end of the base 6 houses the shell represented at 30 which is shown as plainided and carrying an annular outwardly extending flange 31 at its upper end which sets against the u per surface of the base and receives attac iing means such as the nails 32 which are driven through the flungc ill and into the base 6. The shell 30 where of metal. is lined with insulating matm'ial 33 which engages the threaded outer surface of a n'ictal screw-shell 14 lo ated within the shell 30 and thereby insulated from the latter, thc slicll 34 carrying at its lower end a disk 35 of insulating material equipped with a center contact 36, thereby insulated from the shcll 314, these two contacts, namely thc. shcll 1-H and center contart 36. being connected with the electricurrcnt-rondnrr ing wires 2 and 29 which extend upwardly through the open cud ol' the shcll 30. To avoid turning of the shell 34 relatixe to the base 6, I prefernblv indent the shell 84 and insulation 33 as illustrated at 37 a l 38, the insulation interlocking with an opening 3!) in the side of the shell 30.

The lower end of the upri lit 13 in the construction now being descrl ed is equipped with a screwshell 39 of metal confined on the lower end of the upright 13 and insulated therefrom, as throu h the medium of the insaluting lining 40, the shell 39 being adapted to screw into the threaded shell 34 for securely holding the upright 13 and base 6 together and establish electric contact lietween the shell 39 and the shell 34 and the center-contact 41 provided on the lower end of the upright 13 and the contact 36. The center-contact 41 is insulated from the shell 3 by the insulating material 40 and from the upright 15, where the latter is of. electriccurrent-corulueting material, by insulating material 42. The electriccurrent-conducting wires leading from the sockets 23 downwardly through the upright 13 and represented at 28 and 2.) are connected respectively with the shell 39 and the contact 41; and the shell 39 an inmilating material 40 are indented as represented at 43 to interlock the lining 40 with the walls of an opening 44 in the upright 13, for preventing relative rotation of the shell 39 and the upright 13.

While I have illustrated and described certain constructions constituting embodiments of my invention, I do not wish to be understood as intending to limit it thereto, as the sa in may be variously modified and altered without departing from the spirit of my invention.
